naobile-Tires, of whiclrthe following is a flated. WVith the usual pneumatic clear, full, and exact" description.

This invention "relates to an improved automobile tire, one of the objects of which is to provide a non-puncturable resilient tire of durable construction.

The resilient member of my improved tire preferably comprises an inflatable tube, the said tube being removably retained in position and at the same time protected from injury by contact with the ground, or objects upon the ground.

It is one of the objects of my invention to keep the said tube out of contact with the ground, but at the same time to arrange the tire, as a whole, in such a manner as to cause the tube to take the weight of the machine, whereby the resilient, or cushioneffect derived from the air within the tube is maintained.

As a trend, for the tire, 1 preferably em ploy a metal ring, which is adapted to pass around the tube. Between the ring, or tread, and the tube 1 interpose a filler, preferably of wood, although any other material may be used. I prefer to use wood, however, for the reason. that it in itself is more or less a cushion. 5

My improved. the is arranged, as will hereinafter appear, to preclude, to a large extent, the sudden swerving of the machine should a tube become suddenly deflated through any cause whatsoever.

Owing to the protection of the tube, also owing to the fact that the tube does not touch the ground, the deflation thereof through bursting by impact, or leakage by puncture, is largely obviated.

Another feature of my improved tire is the fact that the tread of the wheel. at all times, presents a curved surface to the ground, even though the tube becomes detirc the tread thereof is more or less flattened at the pointof contact with the ground.

My improved tire is retained in position by grooved rings, which may or may not be resilient, the said rings being secured to the felly, or rim of the wheel.

I will now proceed to describe my invention, the novel features of which I will finally claim, reference being had to the accompanying drawing, forming part hereof, wherein- Figure 1 illustrates a side view of a wheel having secured thereto my improved tire, the cover of which is shown as broken away to reveal some of the details of construction; Fig. 2 is an enlarged cross sectional view taken on a line a-a in Fig. 1; Fig. 3 is an enlarged fragmentary view of a wheel and shows a modified form of sccuring means for the tire; Fig. i is a sectional detail view similar to Fig. '2, and shows one Way of securing the tube and lilting piece together; and Fig. 5 is a longitudinal sec tional view taken on a line Z)---l) in Fig. 4-.

Referring to the drawing, 1 indicates a wheel equipped. with my improved tire which is indicated in a. general way by 2.

Referring now to the detailed description of my improved tire, indicates a meumatic, or infiatabletube,which rests in contact with the rim l of the avheel. To hold the tire 8 in position, I have in this instance employed the grooved rings 5 audit. The grooved rings 5 and 6 pass com 'iletely around the wheel 1, as shown in Fig. l; in other words the rings 5 and 6 are independent intcrgral structures, and are secured to the rim 4- of the wheel in this instance, by means of bolts 7. The rim i of the wheel is preferably recessed as at 8 toreceive a projection 9, upon the tube 3, whereby the said tube pre vented from rotating. As can be seen 111 Fig. 2, the tube 3 is adapted to snug ly fit the grooves 10 in the rings 5 and (3. The tube 3 has in contact therewith a filler .11. The filler 11 is j'urcferably made out of wood, and is in'the form of an integral ring which passes completely around the tube 3. As is obvious from the illustration, Fig. 2. the

filler 11 is positioned centrally of the tube 3,

in other words the filler 1.1 is positioned in alinement with the rim 4: of the wheel so that the strain which is transmitted from the'tread of the wheel, by the tube 3 will come directly upon the spokes 12, thence to the hub'13. a

As the filler 11, in itself would in.some cases make a somewhat undesirable tread, I

prefer to encompass the same by a chan-.

neled ring, the portion 14 of which constitutes the tread for the wheel, and the sides of which protect as well as retain the filler 11. The tread 14 of the said ring extends somewhat beyond the sides 15 as indicated by 16. The said extensions are for a purpose to be hereinafter described. The

outer ends of the rings 5 and 6 terminate in lg fianges 17 and 18 respectively, and between -which may be made out of leather, rubber,

canvas, or other material. To secure the dust guard in position, I lace the same, by means ofdaces 24, to projecting rings 25 carried by the rings 5 and6, The tube 3 is provided with "the usual valve nipple for the purpose of introducing air therein.

. It isquite obvious that the weight of the vehicle is transmitted to the wheel proper I through the tube 3, which constitutes an air cushion. A resilientor oushioningeflect is. also transmitted to the vehicle through the give of the said tube when widen-pressure. It is obvious from the construction of my improved tire that the filler 11 transmits strain to the tube 3, and in order that a cushioning effect shall result it is necessary I that the tread ring and filler 11 carried thereby should be movably mounted in the rings 5 and 6. As the machine. travels along, the filler 11 and tread ring will be subjected, to a vertical movement due-to the natural vertical movement of the machine, or more strictl speaking the said filler and tread ringwill remain stationary as far as vertical movement is concerned and the rings 5 and 6, Wheel 1 and the rest 'of the machine will move. up and down. The vertical movement of the machine and appur tenances will be cushioned by the tube 3, the said tube 3 acting asan ordinary pneumatic tire, excepting for the fact that it does not contact with the ground. For the reason that the tube 3 does not contact with the ground, I lengthen its'life and lessen the dangers of rupture, the whole strain'of traction and wear coming upoh the tread 14,

and in the event of tliedust uard 23 being used, the tread of the said ust-guard will take the wear.

Should the tube 3, for any reason, become suddenly'deflated, the wheel 1 would sud: denly lower and if a provision were not nadc themachine would swerve. To prevent the machine from swerving to a dangerous degree is the function of the projections 16 of the tread 14. referring to Fig. 2 it *will be seen that a space '26, whenthe tube 3 is inflated, is provided; this space allows for the come and go of the wheel. Should the tube 3 become deflated, the wheel will only let down to the extent of the space i 26, whereby the amount thata wheel can let downis predetermined by the extent of the space 2.6; the extensions 16am, therefore,

for the purpose of preventing the wheel from letting down to a daiwerous degree. To inflate the tube 3 I empIoy the usual valve 26".

By referring to the modification Fig. 3'

it will be seen that the devices, which hold ,the tube 3 in positiomare composed of independent sectlons 27, the said sections being resilient'and secured to the .im ofthe wheel by bolts 28. It will also be seen in Fig. 3 that with this form of tilamp I do not .tie the outerflanges 29 there f together, as this fornrof clamp is intend d for light vehicles, for which a certain a1 ount of resiliency on the part of the said clamp might be desirable, especially when skids. l.

To prevent dust from passin down between the sides 15 of'the trea ring, and

,the machine .which are adapted to bear-against the said sides '15. in the flanges l7 apd 18 as shown inFig. 1.

To, prevent the tube-3"froni slipping on 'the 'filler' 11 I may cement the said tube and said fillevi together, or I may provide the tube 3 with projections 31, which are adapted to enter recesses 32 in the inner surface of the filler 11, (see Figs. 4 and 5).

It will be seen by the foregoing-description, and drawing, that the tu e, which.

forms part of my invention, is completely inclosed by means of the grooved rings, the

filler and tread thereupon; a portion of the inclosing means (th filler and tread thereupon) being inwardly movable. ,By inclos- "-lhe fiber sections 30 are inserted act - flanges l7 and 18, I provide filier sections 30,

in the tube, as above desc1'ibed, the said tu e is entirely protected from injury and is practically non-puncturable.

Having now described my;inventiom what I claim and desire to'secure by Letters Patent is:

A tire adapted for attachment to the rim of a wheel, comprising a pushioning device,

a channeled ring, surrounding said cushioning devicebut out of contact therewith, a channeled ring, and a tread carried by said filler carried by said channeled ring adapted ring.

to Contact with said cushioning deyicc, w signed at New York city, N. Y., this 24th grooved rings embracing and supporting day of August, 1908. said cushioning device, flanges carried by WILLIAM J. BAUER. said rings adapted to support said channeled ring, and sections of fibrous material carried by said flanges adapted to contact with said Witnesses:
